Definitions

  • This invention concerns rolling bearings and relates more particularly to needle bearings for use in applications such as universaljoints.
  • the invention seeks to provide a bearing construction which in a simple manner will prevent displacement of the bearing from such causes.
  • one end of the bearing race is formed externally with a radially inwardly directed recess arrangement adapted to receive a circular clip, washer or equivalent member for defining a radial flange around said race.
  • the recess may be circumferentially continuous or it may consist of a series of circularly spaced indentations cach adapted for engagement by an internal tooth of a star washer.
  • the recess is a groove circumscribing the end region of the race and, for example in a bearing race which itself is deep drawn or pressed from sheet metal, is most conveniently defined by forming a double fold at the end region of the racc, that is to say, by forming said end region with an axi ally outermost and radially directed fold slightly axially spaced from an adjacent, radially inwardly directed fold.
  • a clip or washer may then be engaged in the recess arrangement to constitute a radial flange external to the race and thereafter preventing the bearing from being withdrawn from the bore.
  • FIG. 1 is an elevation, partly in section of a universal joint incorporating bearings embodying the invention.
  • FIG. 2 is a sectional detail illustrating a modification of the invention
  • FIG. 3 is a sectional plan view with a portion cut away showing another modification of the invention.
  • FIG. 4 is a sectional view taken along line 4-4 of FIG. 3.
  • the universal joint shown in FIG. l comprises a central block which is bored to receive mutually perpendicular shafts, of which one shaft l2 is visible in the drawing. Opposite ends ofthe shaft 12 are received in apertures 16 or arms I8 of a fork member and a needle bearing generally designated 22 is interposed between each shaft end and the arm 18 in 4which it is housed. A second fork member 24 is connected to the central block 10 in a similar manner.
  • the needle bearings 22 each include a plurality of needle rollers 26 located within a cylindrical outer race 28 which is deep drawn from sheet metal'in the form of a cup having a closed outer end 30.
  • the opposite end of the latter is formed with a radially inwardly directed lip or flange 32.
  • the bearing race 28 is then formed, for example by a rolling operation with a second and radially outwardly directed lip 34 which cooperates with the lip 32 to define a recess 36 externally circumscribing the bearing race end.
  • This recess 36 provides a seating for a circlip 38 which, when the bearing 22 is positioned on the shaft 12 is intended to engage behind the arm 18 LII of fork member 20 in order to prevent displacement of the bearing in the event that thrust forces should arise.
  • the bearing may be sealed by an O-ring 40 interposed between the lip 34 and the center block 10.
  • the simple circlip is replaced by an annular washer, preferably of a plastics material such as nylon or polytetrafluoroethylene which has a radial portion 42 for seating in the groove 36 and a substantial axial portion 44 of a depth sufficient to bear against the center block l0 for the purpose both of acting as a thrust washer and also of sealing the bearing against the entry of foreign matter.
  • annular washer preferably of a plastics material such as nylon or polytetrafluoroethylene which has a radial portion 42 for seating in the groove 36 and a substantial axial portion 44 of a depth sufficient to bear against the center block l0 for the purpose both of acting as a thrust washer and also of sealing the bearing against the entry of foreign matter.
  • indentations 37 in the outer race replace the groove 36, and the simple circlip 38 is replaced by a star washer 42 having inward projections that fit in the indentations which are spaced closely enough to prevent loss of rollers prior to assembly of the bearing on the shaft.
  • a bearing comprising an outer bearing race containing a plurality of bearing rollers, the improvement wherein one end of the bearing race is formed externally with a radially inwardly directed recess arrangement to prevent axial movement of the bearing rollers sufficient to fall out of the bearing race, and wherein an annular washer member for defining a radial flange around said race is received within said recess arrangement.
  • a bearing as set forth in claim. 1, wherein the washer member comprises a radial portion engaged in said recess and an axial portion depending from the radially outer region of said radial portion, said axial portion having an axial length substantially greater than the axial thickness of the radial portion.
  • bearing race is deep drawn from sheet metal and the groove is defined by forming a double fold at the end region of the race, said fold comprising an axially outermost and radially directed portion of said end region which is slightly axially spaced from an adjacent and radially inwardly directed race end portion.
  • a universal joint comprising a central block wherein are mounted a pair of mutually perpendicular shafts, said block and said shafts together constituting a cruciform member, a pair of fork members each having apertured arms by means of which a respective fork member is engaged with one of said shafts and a roller bearing interposed between each arm and the shaft portion which it engages, said bearing comprising an outer race, a plurality of rollers contained in said outer race, one end of said race being formed externally with a radially inwardly directed recess to prevent axial movement of the bearing rollers sufficient to fall out of the bearing race, and an annular washer received within said recess for defining a radial flange around said race.
  • each washer member bears against the center block to constitute both a thrust washer and a seal.
